حَدَّثَنَا عُبَيْدُ اللَّهِ ، عَنِ مُبَارَكِ بْنِ حَسَّانَ ، عَنْ عَطَاءٍ ، عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا ، قَالَتْ : سُئِلَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : أَيُّ الْعِبَادَةِ أَفْضَلُ ؟ قَالَ : ”دُعَاءُ الْمَرْءِ لِنَفْسِهِ .“
It is narrated from Sayyidah Aisha (may Allah be pleased with her), she says that the Prophet (peace and blessings be upon him) was asked: Which act of worship is the best? He (peace and blessings be upon him) replied: "A person's supplication for himself."
